Pros
This is one of the best Co to work with if you would like to enjoy freedom, be responsible for your own work, get to do many things at same time, learn many skills, develop your confidence. They have weekly or monthly debrief meetings which are best to improve on your work in minimum possible time and give your best to work assigned.
Cons
Its huge organisation so there is possibility that you have to work extra hours to understand and communicate with many people to get your simple job done. Or you yourself need to have extra ordinary skills to do your task with your own creative tactics. You will like the job if you love travelling and so you need to be energetic to be ready for travel all time, sit in train /plane for long hours, be on your toes if you really wish to excel in your work.
